This “solarpunk” reminds me the universe of Noon from brothers Strugatsky, Soviet science fiction authors (they also wrote Stalker): https://en.m.wikipedia.org/wiki/Noon_Universe , https://en.m.wikipedia.org/wiki/Noon:_22nd_Century

The books were very positive and inspiring: space exploration, communism that worked, a very interesting world to live in.

As nine_k commented, I hope they open Soviet Sci-fi with its interesting aesthetics.

Strugatsky eventually turned from optimism to more pessimistic and tragic future like in “Beetle in the Anthill” https://en.m.wikipedia.org/wiki/Beetle_in_the_Anthill
